Title: Preparation of sol
Inventor: SATO TAKESHI
IPC: C03C1/00
Filed: 1989-03-18
Abstract: PURPOSE:To obtain a sol contg. colloidal particles having two kinds of different particle size distributions by carrying out the hydrolysis of a metal alkoxide followed by peptization in two steps. CONSTITUTION:Part of a prescribed amt. of one or more kinds of metal alkoxides is added to water at 0 deg.C to ordinary temp. of about 30 deg.C and hydrolyzed. After the lapse of 30-60sec after the addition, a monobasic acid such as acetic acid or a monoacidic base such as NaOH is added by 0.1-0.4mol per 1mol alkoxides to peptize the resulting hydrolyzate. The remaining metal alkoxides are then added, hydroxides or hydrates having fine colloidal particles of small grain diameter are formed while controlling the temp. from ordinary temp. to 100 deg.C and heat treatment is carried out at 25-95 deg.C to uniformly increase the particle size of the colloidal particles.

Title: Melt metal treating method and apparatus
Inventor: KURIFUOODO MASHIYUU DANKUSU
IPC: C22C37/04
Filed: 1979-05-30
Abstract: The invention relates to an apparatus for the treatment of molten metal with a reactive additive.The apparatus comprises (1, 2) a pouring cup (4) having an outlet for introduction of both reactive additive and molten metal into a reaction chamber (7). The reaction chamber communicates via a channel (12), preferably of restricted cross-sectional area, with an expansion chamber (15) provided with an outlet (16) for the molten metal. The expansion chamber outlet has a smaller cross-sectional area than the pouring cup outlet (6) thereby ensuring that the reaction chamber is sufficiently filled to cover any reactive additive during a pouring treatment. The apparatus permits a series of pourings to be effected without disas- sembley of the apparatus to introduce more reactive additive.

Filed: 1986-03-26
Abstract: PURPOSE:To attain excellent reception with sufficient reception sensitivity even at a zone of a middle electric field or below by obtaining combining phases of outputs of plural antennas so as to obtain a desired directivity. CONSTITUTION:Plural television reception antennas 1-4 are mounted to a car body, outputs of the antennas are fed to a combiner 9 via variable phase shifters 5-8 respectively to combine the phase and the result is fed to an antenna input circuit 10 of a television receiver. On the other hand, the level of the antenna input circuit 10 is detected, the combination of phase shift quantities of the variable phase shifters 5-8 is decided corresponding to the highest level in the detected levels and the combination of the phase shift quantities of the variable phase shifters 5-8 is converted sequentially in the vertical blanking period of a television video signal based on the decision. Thus, the optimum directivity is obtained always in all directions and various disturbances such as flatter or ghost are prevented.

Filed: 1991-03-08
Abstract: PURPOSE:To dispense with independent counter electrode, reference electrode and so on, and use a mere single piece as a stable electrode by arranging a noble metal electrode so as to be in one united body with a micro working electrode. CONSTITUTION:A bipolar-integral microelectrode is constituted of a carbon fiber 3 whose one edge is supported with the tip of a glass pipet 2 and the other edge is connected to the first lead wire 61 and a platinum electrode 5 which is integrated in one body in a part of the pipet 2 and whose one edge is connected to the second lead wire 62. Because of difference in electric potential impressed between the fiber 3 and the integrated formed electrode 5, an object to be measured is oxidized or deoxidized, so that electric current is flowed. Since flowing current volume has a certain correlation with concentration of the object to be measured, the concentration of the object to be measured can be recognized by measuring the current volume.

IPC: A63F7/02
Filed: 1996-03-25
Abstract: PURPOSE: To automatically supply game balls without troubling any human labor by providing a pachinko game machine with a game ball supplying means for automatically supplying the game balls based on the detection output of a remaining amount detecting means concerning the game balls in a supply tray. CONSTITUTION: It is detected by the remaining amount detecting means whether the number of balls on a supply tray 102 is more than a prescribed amount such as 20, for example, or not and when it is decided that the number of balls is less than 20, it is detected whether the number of balls on a reception tray 103 is more than a prescribed number such as 25, for example, or not. When it is judged that the number of balls on the reception tray 103 is more than 25, after all the balls on the reception tray 103 are extracted by operating a ball extracting device 50, the balls are simultaneously replenished to the supply tray 102 25 by 25 by operating a ball lending device 40. At such a time, the number of bought balls in the RAM of a CPU is not increased but the number of balls to be extracted from the reception tray 103 is decreased just for 25.  Besides, when it is judged that the number of balls in the reception tray 103 is not more than 25, it is judged whether the sum of the number of remaining balls after the extraction of balls from the reception tray and the present number of balls in the reception tray is more than 25 or not and when it is more than 25, the balls are fed back from the reception tray but when it is less than 25, the bought balls are replenished.

Title: Apparatus for detecting direction of line of vision for use in vehicle
Inventor: ISHIWAKA TAKUO
IPC: G02B27/00
Filed: 1994-03-11
Abstract: PURPOSE:To exactly detect a direction of a line of vision even when a driver wears eye glasses. CONSTITUTION:A driver's watching part of a line switch area 26 displayed by HUD is judged by a line stop-detecting part 23, whereby various kinds of controls are effected via a controller-switching part 27 correspondingly to the watching part. In a line switch system constituted as above, in order to obtain a direction of a driver's line of vision, a reflecting image from the retina is obtained by a retina reflecting image-extracting part 7 from image data photographed by a camera 4 when an eye ball 13 is illuminated by divergent, illuminations 1, 2, and a center of the pupil is obtained. A reflecting image from the cornea is extracted by a cornea reflecting image-extracting part 8 on the basis of a position of the retina reflecting image. A direction of the line of vision is thus obtained by a line direction-calculating part 10 based on the center of the pupil and the cornea reflecting image. At this time, a size of a light source of the divergent illumination l having an optical axis agreed with that of the camera is set so that a reflecting image of the light source formed by eye glasses on a photographing surface of the camera is smaller than a minimum diameter of the pupil. Accordingly, the retina reflecting image can be easily distinguished and separated from a reflecting image by the eye glasses through comparison of areas of the images, and the direction of the line of vision can be calculated highly accurately.

IPC: H04N5/217
Filed: 1988-03-24
Abstract: PURPOSE:To suppress shot noise without taking any frame correlation by applying a multiple of a constant number to a difference giving a minimum absolute value to an electric signal when the minimum absolute value least in the absolute value of a difference between plural proximity signals and the electric signal is smaller than a prescribed value. CONSTITUTION:A signal string inputted from a terminal IN is delayed by one output by a delay circuit 1 and a differential amplifier 2 takes a difference signal Si-1-Si. The signal is inputted to a suppression signal generating circuit 3, and a multiple of a constant alpha of the signal Si-1-Si, that is, alpha(Si-1-Si) at a prescribed value ai or over is outputted and 0 is outputted at the value ai or below. The output is added to the signal Si to attain noise suppression. The value ai is a constant representing the noise depending on the signal Si and in case of a short noise, the value ai is proportional to the root of Si. Thus, it is possible to suppress shot noise of an incident light without taking frame correlation.
